DTF降茶氟剂降茶氟初步研究

目的探讨DTF制剂降茶氟效果。方法在不同制茶方法程序中加入DTF制剂观察其降氟效果。结果在冲泡或煮沸(1.0g茶叶,200ml水量)沏茶中,0.2gDTF可使茶氟降低约60%,使茶水氟浓度由2.0～4.0mg/L降到1.0mg/L左右,茶液色、味、pH值无改变。结论DTF是1种有效的降茶氟剂。     

初次吸毒者与复吸者戒毒期间生活质量比较

目的:了解包头市初次吸毒者与复吸者戒毒期间的生活质量。方法:用QOL-DA2.0量表对戒毒人员的生活质量进行调查。结果:初次吸毒者与复吸者各纬度进行t检验显示躯体功能纬度(t=10.51)、心理功能纬度(t=5.94)、症状及毒副作用纬度(t=6.41)、社会功能纬度(t=10.47)和总分(t=10.48)均有统计学意义(P<0.001),表明戒毒期间初次吸毒者的生活质量高于复吸者。结论:在戒毒期间初次吸毒者的生活质量较复吸者易改善。     

六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。

联合菌苗抗肿瘤作用的初步探讨

目的 :探讨联合菌苗防治肿瘤的作用。方法采用动物体内实验 ,动物为封闭群KM小鼠 ,菌株为 2 6 0 0 3- 2 1、4 482 4 - 3及 932 0 1- 3,瘤种为S180 。所有实验小鼠接种S180 后 ,按随机对照试验设计分成 5组 ,即三个不同的单价菌苗组、一个联合菌苗组及一个对照组 ,同期观察联合菌苗对S180 增长的影响。结果 :三个不同的单价菌苗组及联合菌苗组的平均瘤重均比对照组低 ,联合菌苗组的平均瘤重比单价菌苗组的更低 ,差异均有高度统计学意义 (P <0 .0 1～ 0 .0 0 1) ;三个不同单价菌苗组的抑瘤率分别为 5 0 .6 %、4 8.3%、4 5 .5 % ,联合菌苗组抑瘤率为 75 .0 %。结论 :实验所选用的菌苗能抑制S180 的增长 ,联合菌苗的效果更好     

海脉冲营养素对小鼠造血功能的影响

通过与复方阿胶浆，施普端螺旋藻胶囊抗贫血功效的比较，研究了海脉冲营养素对小鼠造血功能的影响。结果表明，小鼠口服ＨＭＣ５００ｍｇ／（ｋｇ．ｄ），对失血性贫血小鼠有提高，ＲＢＣ的作用，对苯肼引起的溶血性贫血小鼠有升高Ｈｂ，ＲＢＣ，ＷＢＣ的作用，能促进由环磷酰胺所致骨髓抑制小鼠的骨髓有核细胞的增殖，增加脾脏重量，升高外周血中网织红细胞和ＷＢＣ数量。     

Constraints on Social Activities of Care-Givers: A Sociological Perspective

Newer policies of community care for those with disabilities have resulted in the home becoming the usual site of care. Policy makers must now give attention to the needs of those at home giving this care. This article explores the constraints on sociability opportunities of 73 mothers who were caring for children with disabilities. These opportunities are often built into leisure pursuits for women without caring responsibilities. However, choice of out-of-house leisure activity was circumscribed for the mothers in this study and their reported leisure activities revolved around home and neighbourhood. Even these sites offered limited scope for sociability because of the way in which caring affected domestic space and because of the characteristics of the modern Australian suburb. It is argued in this paper that personal time and personal domestic space are needed by care-givers so their sociability needs can be fulfilled. An understanding of the constraints imposed by use of the home as a place of care may make possible the planning of a rearrangement of domestic space to increase sociability opportunities for carers.     

Anatomic bases of tongue flaps

Summary The morphological structure of the lingual a. was studied in 50 dissected and 14 vascular cast specimens. The course of this artery is divided into 4 segments: the original segment, the segment within hyoglossus, the ascending and the horizontal segments of the deep lingual a. The root of the tongue is supplied by 2 to 3 root branches of the lingual a., the ascending palatine a. and the tonsillar a. The body of the tongue is nourished on average by 25 arterial branches from the deep lingual a. The ventral surface of the tongue, as well as the sublingual gland and the floor of the mouth, is supplied by the sublingual a. The termination of the lingual a. anastomoses with the submental branch of the facial a. to form the lingual frenal a. Except for a submucous arterial network on the dorsum of the tongue, all blood vessels are separated completely by the lingual septum, through which arterial anastomoses (2.0 mm in diameter) can be found occasionally.This work was supported by the National Natural Science Fund
